A shot-blasting machine for cleaning a surface of a linear metal element (2), such as a metal rod, a metal wire and the like comprises at least one rotor (6; 26) capable of projecting a jet of shots (8) against a surface of the linear metal element (2) and guiding pulleys (1, 3, 4, 5, 9, 11) for the linear metal element (2) capable of directing in the field of action of the jet of shots simultaneously at least a first (210) and a second part (220) of the surface of the linear metal element (2). In the machine, at least the first (210) and second part (220) of the surface are kept by the guiding pulleys (1, 3, 4, 5, 9, 11) under the jet of shots (8) substantially on a same plane, side by side and at a prefixed close distance (dv) at least for the whole path travelled by the linear metal element (2) in the field of action of the jet of shots (8).
